I am a commercial and independent film sound designer with originally recorded and synthesized sound effects available for cheap or free, depending on the size, scope and timeline of the project. I also have experience implementing in the Unreal Engine, but my forte is creating original sounds, ambiences, and effects. Thanks for reading and please feel free to message me if you are in need of effects, or would like to hear samples. Thanks!
P.S. You can hear a few examples on my new soundcloud and blog dedicated to field recording but I cannot post commercially used samples there.Soundcloud.comSoundcloud.com

Well, there is probably about a million ways to approach something like this, and it depends on the direction you would like to take it and the theme of the game. If you send me a PM I would be happy to advise you.
